Hydraulic hose DN20 1SN ULTIMATE 135deg. 105 bar

Construction of the DN20 1SN hydraulic line

The DN20 1SN Ultimate 135°C 105 bar hydraulic hose is a flexible high-pressure line designed for transporting hydraulic oil in industrial and mobile installations. The DN20 designation indicates a nominal internal diameter of approximately 20 mm, allowing for higher medium flow compared to smaller diameters while maintaining system stability. The 1SN construction signifies a single steel wire reinforcement braid, providing resistance to operating pressures up to 105 bar. The core is made of synthetic rubber resistant to mineral oils, while the outer layer is designed for operation at elevated temperatures up to 135°C. The design meets the requirements of EN 853 1SN and ISO 1436 standards, which define strength parameters and operational safety.

Practical application of the DN20 105 bar hydraulic hose

The DN20 1SN 105 bar hydraulic hose is used in systems powering hydraulic cylinders, valves, and actuators in agricultural, construction, and industrial machinery. Due to its larger nominal diameter, it is used where higher volumetric flow is required at moderate pressure. Increased temperature resistance up to 135°C allows the line to be used in installations operating under increased thermal load. This is particularly important in machines working continuously, where hydraulic oil temperature can rise significantly.

Differences between DN20 1SN and other line variants

Compared to 2SN lines, the 1SN hose is lighter and more flexible, making it easier to route in confined spaces. However, its operating pressure of 105 bar indicates it is intended for medium-load systems. In systems exposed to high pressure spikes or impulse work, double steel braid hoses should be considered. The Ultimate 135°C version differs from standard 1SN lines by its increased heat resistance, which translates into a longer service life in harsh operating conditions and a lower risk of rubber degradation.

Common DN20 hydraulic line selection errors

The most common error is failing to account for the actual operating pressure and medium temperature. Selecting a line solely based on the DN20 diameter without analyzing installation parameters can lead to shortened hose life. The minimum bend radius must also be observed, and twisting the line during installation should be avoided. Equally important is the quality of the crimping. Improperly selected ferrules or an incorrectly performed crimp can cause leaks and failures of the entire hydraulic system.

Custom production of hydraulic lines at Hydron

Hydron offers the DN20 1SN Ultimate 135°C 105 bar hydraulic hose both in commercial lengths and as ready-made lines crimped according to customer specifications. It is possible to customize the length, type of fittings, and configuration for a specific machine or installation. Constant stock availability and technical support allow for quick line preparation and reduction of operational downtime.
